After enjoying the simplicity and reliability of Firefox's link sharing to any device you have the browser installed on for years, I've found flow so comically bad that it's likely going to push me back to Firefox.
Between Flow disconnecting, not showing links and the limitation and hassle of having to connect all my devices independently of logging into the browser with my Opera login, I just can't imagine how any developer thought this feature was sufficient. It's less hassle for me to message myself links to open via FB messenger on another device.
That's all. Enjoy your day.
